The areas on your body where you have really thin and delicate skin is also painful, I have a tattoo on my upper arm, and while most of it didn't hurt much, the part that is wrapped around and sort of almost reaches my armpit hurt a LOT more. I've heard tattoos on your stomach/side hurts too, even though those are kind of meaty areas. Don't quote me on that though, I only have one tat.
(Also don't worry about 'killing' the thread, you didn't. Threads here just nap a little sometimes, it's not anyone's fault.)
